I don’t know about you, but if I messed up my hands, my life would really start to suck. I’m a software developer and musician; if I lost fine motor control or sensitivity, I’d be out of a job and my favorite hobby/activity all at once.
Gloves protect you from the elements, from yellowjackets, from chunks of rock and asphalt flung up by truck tires, and of course, from road rash and broken bones in the case of an accident. Open fingered gloves might feel better or look better to you, but motorcycle gloves don’t come with open-fingers. If you have half-finger gloves, you’re probably using a pair of lifting gloves or driving gloves, in which case your virtually unprotected. Those aren’t meant to crash, and as you now know, they don’t keep your hands protected when you’re on the bike either.
Get yourself a pair of legit motorcycle gloves. They’re a huge range, in both style and price, from $30 wrist-length vented mesh to $400 double-thickness kangaroo race gauntlet. There’s gotta be something for you in that range. If not, you might as well not well gloves at all.
